white. Mouth curved, a little broader above and below tban in 

 the middle. Outer lip rises very little above tbe top, bending 

 out, a very little yet at once, from tbe apical pore : it is strongly 

 curved tbrougbout. Top is small, sligbtly oblique, with a 

 scarcely definite feebly scored rim, within which is a funnel-shaped 

 perforation. Inner lip : a thin glaze, with an irregular edge 

 spreads across the body, which is well rounded : round the base 

 of the oblique pillar is a feeble furrow and fold ; the lip-edge is 

 appressed, and has behind it a very slight depression, but no 

 umbilicus. L. 0'106. B. 0*056. B. of mouth at same place, 

 0-013. 



This species is very like 0. reticulata, but differs from it in 

 that the shell is broader in proportion to length ; the mouth is 

 broader and more curved ; the strongly reticulated sculpture is 

 absent, what there is being much feebler and less regular*, 

 this is especially the case with the longitudinal furrows ; the 

 outer lip rises less high behind and does not lean in at all to the 

 perforation ; the edge of the top is less oblique ; the pillar-lip 

 has a fold at its base, and the lip^edge is reflected and appressed, 

 and has no umbilicus behind it. 



7. Ctlichna I/ABiata, n. sp. 



Oct. 6, 1874. Amboyna. 15-25 fms. 



S]iell, — Small, strong, oval, obliquely truncate above, where 

 the apex is impressed, bluntly pointed in front, obscurely 

 angulated above the middle, umbilicate, finely and closely striate, 

 with a thickened lip posteriorly produced. Sculpture. Longi- 

 tudinals — there are fine, straight, hair-like unequal lines of 

 growth. Spirals — there are fine spiral lines, which at the top 

 and bottom of the shell are a little strong and remote, but in all 

 the centre part are very faint and crowded, and above the middle, 

 where a very blunt angulation occurs, they are nearly invisible. 

 Colour translucent white, with a tinge of brown, which on the 

 oiiter lip and base is ochreous. Mouth long, curved, narrow, 

 a little enlarged in front. Outer lip rises perpendicularly trom 

 the outer edge of the impressed apex, is produced posteriorly, 

 where it bends in toward the apex, and is patulous and almost 

 emarginate; its direction and edge-line are both somewhat 

 flexuous ; in front it is contracted in towards the pillar, forming 

 at the point of the base a narrow, patulous, but not emarginate, 



* Hence the name.
